Feasibility of hydrogen production from cellulose and prediction of the product distribution : thermodynamics analysis

High carbon emissions, depleting fossil energy reserves have become a global problem. It is necessary to develop renewable energy sources that are environmentally friendly. Hydrogen (H2) is one of the energy sources and carriers that can be developed. This gas can be produced from renewable, sustain...
